WLADIMIR LIVTSCHAK, OF ST. PETERSBURG, RUSSIA.

No. eoaec/e.

To all whom it may concern:

Be it known that I, WLADn/nn Lrv'rsonAK, a subject of the Emperor ofRussia, residing at St. Petersburg, in the Empire of Russia, haveinvented a new and useful Harvesting-Mac hine, of which the following isa specification.

My invention relates to improvements in harvesting machines, whereby itis rendered possible to heap or pile the cut crop in a space on theframe between the main wheel and the finger bar and to discharge same indefinite heaps upon the ground so that free space is left for the pathof the draft animals, and the subsequent binding up into sheaves by handis facilitated..

l will now proceed to describe my invention with reference to theaccompanying drawings, in whichh Figure 1 is a side view of myharvesting machine, the drivers seat being omitted, Fig. 2 is a plan ofthe same including the drvers seat, and Fig. 3 is a vertical sectionthrough a part of the machine on the line Air-B in Fig. 2.

Similar characters of reference refer to similar parts throughout theseveral views.

divide the frame work into two frames 1 and 2, which are rigidlyconnected together in the same horizontal plane by means of suitablescrews and nuts or their equivalents. The framework so formed issupported by two wheels 3 and 4 on opposite sides as will be hereinafterdescribed. The frame 1 is made long and rectangular' and comprises anendless apron 8 of sail-cloth or the like,

` which is strengthened with cross bars 7, 7

and passes over two rollers 6 and 61. The one roller 61 is journaled insuitable bearings (not shown), which in any known manner can behorizontally adjusted on the frame 1 for taking up any slack of theapron 8. The other roller 6 is fastened on a shaft 33, which is mountedin the frame 1 to turn and is driven from a shaft 13 to be hereinafterdescribed, by means of bevel wheels 24 and 25. Above the roller 6 avertical board 9 is secured on the frame 1 and another vertical board 34is secured on the opposite side of the frame 1. This board 34 is notvisible in Fig. 2, as it is hidden by the ordinary divider-shoe 35 ofany known construction. On the board 34 is fastened a pin 36, on whichthe lateral wheel 4 is mounted to turn.

" The frame 2 is arranged for containing the Specification of LettersPatent.

main wheel 3 and is made narrow so as to compensate for the excess inlength of the frame 1. The ordinary drivers seat 37 is attached to theframe 2 in any known and approved mannen The shaft 38 of the main wheel3 has fastened on it a large chain wheel 10 which is arranged to driveby means of an endless chain 12 a small chain wheel 11 loose on theabove mentioned shaft 13. The latter is mounted in the frame 2 to turnand can be coupled at will with the chain wheel 11 by means of a clutch39 of any known construction. The shaft 13 drives by means of bevelwheels 14 and 15 a shaft 40 with a crank disk 41 for reciprocating theknife bar 42 with the aid of a connecting rod 43. On the front side ofthe frame 1 is fastened a finger bar with the fingers 44, 44, in whichthe knife bar 42 is guided as usual. The finger bar extends over onlythe larger part of the front side of the frame 1, so that there is lefta space between it and the vertical board 9.

On the frame 1 are fastened two crossing studs 45 and 46 to which thepole 5 is attached in any known manner. On the front side of the frame 1is fastened an inclined stud 28, on which a metallic segment 47 isfastened. A horizontal shaft 48 is fastened in the crossing point of thetwo studs 45 and 46 and in the inclined stud 28, and on this shaft 48 asleeve 49 is mounted to turn. This sleeve carries at its ends two chainwheels 19 and 191 and near them two cast pieces 50, 50, on which twoparallel long arms 26, 26 are fastened. These arms carry on their endstwo blades 27 and 271 and form a discharger as will be hereinafterexplained. A beam 51, 511 with a bracket 52 on its middle is mounted onthe shaft 48 to rock and carries on its arm 51 a suitable bearing 53 forthe shaft 54 of a reel 16 of any known construction. The segment 47 isprovided with several holes 55, 55, through any one of which a pin 56can be introduced for engaging in a hole or recess in the arm 511. arm511 up or down the reel 16 can be lowered or raised in accordance withthe height of the crop, after which the reel 16 can be secured in itsposition by means of the pin 56. On the stud 46 is fastened a suitablebearing 57 for a shaft 58 carrying a large chain wheel 18 and a smallchain wheel 181. On the shaft 13 is fastened a small chain wheel 17,which is connected with a large chain wheel 18 by an endless chain 21,while the small By turning the chain wheel 181 is connected with thelarge chain wheel 19 by an endless chain 22. In this manner thedischarger can be put in a slow rotation in the direction of the arrow59 in Fig. 1 from the driving shaft 13. As the large chain wheel 191 isconnected by an endless chain 23 with a smaller chain wheel 20' fastenedon the shaft 54 of the reel 16, the reel 16 can be at the same time setto rotate at a larger speed in the direction of the arrow 6() in Fig. 1.On the inclined stud 28 is fastened a bearing 61 for a rocking shaft 62,which carries two arms 63 and 64. A helical spring 65 surrounding theshaft 62 and attached with its one end to the bearing 61 and with itsother end to the arm 64 tends to press the two arms 63 and 64 into theirnormal position shown in full lines in Fig. 1, so that the arm 63 isapproximately horizontal. This arm 63 is provided on its free end with abent fork 30 and serves as a detainer as will be presently explained.The other arm 64 engages in the path (marked by a dotted circle 66 inFig. 1) of two fingers 31 and 32 fastened on one arm 26.

The machine is shown as provided with a device for raising and loweringat will the combined frames 1 and 2 in accordance with the desiredheight of the stubble. However, I do not further describe this device asit is old and is immaterial to my invention, also it maybe of any otherknown construction.

'Ihe harvesting machine operates as follows: After putting the animal oranimals to the pole 5 the machine is driven to the starting point of afield, whereu on the driver engages the clutch 39 in any iown manner forputting the driving shaft 13 in rotation. rIhe reel 16 will incline thestalks of the crop and the knife bar 42 will cut the crop. The cutstalks falling on the endless apron 8 will be moved by the latter fromright to left (when looking forward in the direction in which the animalor animals go on), that is, toward the right in Fig. 3, so that thematerial accumulates deepest where it rests against the board 9. Oneither nger 31 or 32 of the discharger striking the arm 64 the detainer63 will be lowered, so that its fork 30 will engage in the heap ofstalks (see Figf3) and detain the cut crop behind the knife bar 42, inother words, it will prevent them from vfurther moving with the apron 8and thus permit the pile formed to separate. The res ective blade 27 or271 of the discharger will t en strike the lower ends of the accumulatedstalks and thereby move the pile rearwards. On the finger 31 or 32leaving the arm 64 (which with the detainer 63 at this moment occupies aposition indicated by dotted lines in Fig. 1), the detainer 63 under theaction of the helical spring 65 will recoil to its initial position sothat it -is withdrawn from the crop. At this moment or shortlyafterwards the discharger will have discharged the heap or pile of cropto the ground, and the apron 8 will continue moving the cut crop towardsthe board 9.

.From an examination of Fig. 2 it will be clear that the dischargedheaps or piles of crop are in a line at a distance from the uncut crop,which distance is ample for giving free way to the animal or animals intheir next turn. The binding up of the heaps or piles into sheaves byhand is also greatly facilitated.

I am aware that it is old in mowing and rea ing or harvesting machinesto employ end ess a rons running in a direction at right ang es to thedirection in which the animal or animals draws or draw the machine, butsuch machines have all so far failed to work satisfactorily, chieflyforthe reason, that the length of the apron, that is the distance of itstwo driving rollers, is approximately like the length of the knife orlinger bar, in other words like the breadth of the strip of the field inwhich the crop is being cut. In opposition to such known machines I makethe endless apron longer, about like the breadth of the strip in whichthe crop is being cut plus about one third of same, so that the heaps orpiles of cut crop are periodically discharged on a strip of surfacewhich adjoins the said strip of the field, and I dispose the specialdischarger (which forms the chief feature of my invention) in the spaceon the frame 1 between the finger bar and the vertical board 9, in otherwords above the strip of surface on which the heaps or piles are to bedeposited. In accordance with this I reduce the usual breadth of theframe destined in ordinary machines for the main wheel and the drivinggear and I employ the narrow frame 2 described above.

The spring-pressed detainer 63 forms another feature of my invention andserves for facilitating the eriodic discharge of the several heaps or pies formed.

The machine may be varied in many respects without departing from thespirit of my invention.
